【 摘 要 】
Indium tin oxidenanoparticles were synthesized in two different sizes by a nonhydrolytic sol-gelmethod. These powders were then transformed into ITO via an intermediate metastablestate at between 300 and 600 ºC. The presence of characteristic O-In-Oand O-Sn-O bands at 480 and 670 cm-1 confirmed the formation of ITO.The X-ray diffraction patterns indicated the preferential formation of metastablehexagonal phase ITO (corundum type) as opposed to cubic phase ITO when the refluxtime was less than 3 h and the heat treatment temperature was below 600 ºC.Particle morphology and crystal size were examined by scanning electron microscopy.
